Package: caps
Version: 0.9.24-5
This has been tested on a Stretch system from the stable package version
(0.9.24-4) as well as from a home-made backport of the current
buster/sid package (0.9.24-5).
The following plugins aren't working :
- C* AmpVTS
- C* Compress
- C* CompressX2
- C* Saturate
When one of these plugins is inserted into Ardour, an audio click is
happening and the track's meters is going up in the red and stays there.
The attached patch fixes the issue on a debian stretch rebuild.
It hasn't been tried by me so far (hence this report and not a commit to
the debian salsa repository).
Notes:
1) this patch has been sent to the upstream maintainer
2) I'm copying the patch writer to this bug report, please keep him
CC'ed for any later message on this thread
Hope that helps.
